PROMETOPIA ROTUNDATA. 75 



NOTE XIX. 



TWO NEW SPECIES OF COLEOPTERA 



COLLECTED DURING THE RECENT SCIENTIFIC 



SUMATRA-EXPEDITION. 



DESCRIBED BY 



E. REITTER. 



1 , Prometopia rotundata , sp. n. 



Rotundata , leviter convexa , nitida , glabra , subtus fusca , 

 antennis pedibusque ferrugineis , supra nigra , subtilissime 

 dense punctulata, lateribus prothoracis elytrisque, bis ma- 

 culis magnis subrotundatis rubris, serie sublaterali puncto- 

 rum fortiter insculptis. — Long. 3,5 mm. 



Almost circular , slightly convex , upper surface glossy 

 black , closely and very finely punctured , the prominent 

 lateral margins of the thorax and elytra and moreover two 

 large and roundish spots on each of the latter bloodred. 

 Head with two faint impressions between the antennae. 

 Thorax strongly narrowed towards the front margin , the 

 anterior as well as the posterior angles acute , the anterior 

 angles produced. Elytra nearly semicircular , and provided 

 close to the slightly upturned lateral margins with a well- 

 marked row of punctures, ceasing at a rather considerable 

 distance from the apex. 



This species may be easily distinguished from Prometo- 

 pia quadripunctata Rttr and quadrimaculata Motsch. by its 

 circular shape.
